Vape cracker

[Banzai250]

Can someone please explain to me how some of rda sounds cracker when they’re vape ? I saw a video on YT that this guy make everything he build rda/rta/boro sounds firefly angry with popping sounds ? I notice he only used Red’s artisan coil on all his builds so it’s it the coils or the way he wicks that resulted those sound?

Crackling and popping from an rba is usually due to underwicking.

Air pockets in the wick.
